It will be observed that the trunnions 40 arespaced from the ends of the forked portion of the key snap which restupon or adjacent the washer 25.

In the position of the parts as illustrated by .Fig. 2, the key snap 38is lying flatly upon the surface of the flange 9 and the balls 32 arepressed by the energy of the spring 33 against the surfaces ofthe'conical portion 26 and against the shank of. the pin .24. Thus thecover sections are held in proper binding relation. However, by

manually lifting the outer end of the key snap 38 until it is in theposition shown by Fig.3, the

forked ends 39 engage the washer 25, theyjslide thereon, and the. stud36 is drawn outwardly against the force exerted by the compressionspring 33. Then the pin 24 is released andcan 'be withdrawn from thecore 27; If desirable the stud 36 can be unscrewed from the stem 34 andthe key 35 removed entirely, thus permitting the ,locking device to"remain-locked to the pin 24,

The binder canthen be tightened by pressing thefianges 9 toward eachother, but cannot be unbound until the key is applied and manipulated inthe manner described. It will be notedthat thekey snapin itsextremeoperative position-as shown'by Fig. 3, extends in a direction axially ofthe cylinder 22 orat right-angles te -the. bar 8. In this 'position -thekey snap is in its dead-center position with respect to the spring3 3and it then canbe made to snap automatically in either -di-* rectionuntil it lies substantially flush-with--thesurface of the flange 9.In'manipulating'the'key snap- 38=the forked ends 39 thereof perform acam-like action'upon the washer 25 and extend through the openings 42 ofthe flange 9 which register withthe washer. Suitable n'otches 43 in thestrips 11 receive the casing 22 and-pin 24 when the parts of the deviceare in assembled relation. ,--From the foregoing description it will beapparent that the construction embodying themvention provides for'theproper securing together key.

"Although only one form ef the invention has been shown and describedin:' detail it will be apparent to those skilled in theart'that theinvention is not so limited'but that various changes may be made thereinwithout departing from the spirit of the invention or from the scope ofthe appended claims. v 1 -i What is claimed is:-

, 1'. In a loose leaf binder, a pair-of binder sections movable towardand away from each other;

leaf-receiving posts projecting inwardly in or:- posite directions fromthe sections, telescoping clutching members secured to the sections forreleasably securing the sections in binding relation, one of theclutching members having a spring normally maintaining said members inclutching relation to permit movement of the sections toward each otherbut positively opposing separation thereof, a keyremovably secured toone .of-the clutching members, said key including a member havingcamming action upon one of the sections to force said one of theclutching members into inactive relation against the action'of thespring, said member adapted when partially returned'to automaticallysnap back into inoperative position, whereby the clutching members areagain active in preventing separation'of the sections.

2. Ina loose leaf binder, a pair of binder sections movable toward andaway from each other, leaf-receiving posts projecting inwardly inopposite directions from the sections, means for re:

movably mounting the posts in the binder, a one-way clutching mechanismsecuringthe sections together,'-a key removably connected to one portionof the clutching mechanism for controlling the clutching mechanism, saidkey in-'" 3. 'A manipulating device for loose leaf binder fastenerscomprising a body portion having fastening means thereon, and a memberhaving a pivotal connection on the body portion, said member having amanually operable extension on one side of-the pivotal connection and abinder-engaging extension on another side of the pivotal connection. 4.In a loose leaf-binder, a pair of separable binder sections,f-postsmounted upon the binder sections, interfitting clutching members on thesections having cooperating parts operable toprovideclutching-engagement between said mem bers in anyinterfittingposition for maintaining them in book-like form,-a key for operatingsaid members'to disengage said cooperating parts of the clutchingmembers, and resilient means for normally actuating said clutchingmembers into clutchin g'relation, said key having coacting. connectionwi'th one of the clutching members and means cooperating with one ofsaid binder sections movable to produce a snap action of said key into aposition to insure automatic locking of the clutching members.
